Head cysts usually refer to scalp cysts. The specific cause may be related to infection, trauma and other factors. In addition, cysts may also be caused by parasites, which are parasitic cysts caused by parasitic infection, and a few are cystic changes of tumors. In clinical practice, most patients have local scalp inflammation, redness, swelling, heat and pain, and local purulent substances. If the symptoms are not serious, oral antibiotics can be used for treatment, and the cysts of most patients can be absorbed by themselves. If the cyst infection seriously causes local skin ulceration, or compression can cause symptoms, such as headache and epilepsy, it is recommended to go to a regular hospital for surgery in time, remove the cyst and purulent substances, and change the dressing regularly, so that it can be completely cured.
